\ To all whom t may concern.'

Be' it known that I, Aivromo Parmi, a, 'subject of theKing ofltaly, and havingresided. in the UnitedV States one year last past and having declared my intention of becominga citizen thereof, residinflr in the ing the'fluid.-

The inventiimV is satisfactorily illustrated in theacoompanyingldrawing, but the iin- 'portant instrumentalities thereof may be varied., and so it lis'to be understood that the invention :isnot limited to the specific de?y tails shown and described, as long as they are within the' spirit or scope of the claims. Figure 1 represents a vertical sect-ion of an electrically operated fluid heater embodying my invention.

F ig. 2' represents atop plan thereof. F'g. represents a horizontal section on the line 3 3 of Fi 1.

Similar numerals of, reference indicate corresponding parts in the figures.

heferring to the dra-wings: 1 ydesignates a fluid receiving chan'i'ber, and 2 designates thc;b cap or cover thereof. 3

designates a divisional diaphragm between the top of the chamber 1 and the bottoni ofV t-he cap 2, its lperipheral portion being seated on the shoulder 4 of the chamber 1, packing 5 being imposed to form tight joints for said chamber, cap anddia hragm.

In `the diaphragm 3 is t e seat 6 for thev valve 7 Whose stem is engaged by, the spring 9, and fitted slidingly to the pin 10, in the cap 2, said pin being adapted to form a guide forsaid stem, it being connected with the top of the cap 2 by the nut ll.

l2 designates a lever which is pivotall)r mounted on an ear in the cap 2, passed freely throuvh the-valve stem S and connected by the piece 13 of insulating material with the bracket or elbow 14, whereby the latter Specication of Letters Patent.

ELECTRICALLY-OPERATED FLUID-HEATER.

Patented May 4., 1920.

Application filed August 11, 1919. Serial No. 316,553.

1is adapted lto be raised and lowered by said ever. i .i

Connected with the diaphragm below the bracket 14 is the electrode 15 connected wich which is the bracket or elbow` 16, both bramets being within the efap 2, and hav-ing therein opposite limbs provided respectively with the electrodes or contacts. 17 i which are adapted to make and break an; electric cir cuit. by the movement of the bracket 14, as

,will be, hereinafter described.

1S designates an electric wire or conductor which is connected with the bracket 14,and with the electrode 119 on cap-2, said electrode having also connected ivith'itthe electric conductor 20. v

'Within the receiver -1 istheheating element '21 which is composed ofna piece' of ivire bent in zig-zag, spiral, coil or .other form, one end of the saniebeing connected with the electrode 15- bythe binding'screw 22, and its botherend` 'beingY connected'with the conductor 25,' as hereinafter described, said element thus-being in 4an electric' cir-l cuit with said conductors-Quand 25A4 f H The chamberl is rovided with the inlet neck 23 which is a a ted to be connected with asource of supp y .of'flui'd for direct# ing the latter into the chamber.

The cap 2 has connected with it the nozzle 1 .or spout 2--1 for the discharge of the 'fluid 'from the same.

'The operation is as follows The fluid is 'turned' on from4 its 'source whereby it enters ther chamber 1 and fills the same. The inow of the'luid and consequent upward pressure of the same lifts the valve T from its seat and so opens it; A The valve stem 8 raises theV lever 12 whereby the bracket 14 is also raised and itsl contact17 is engaged with the contact on the 'bracket 16,

and so there is a circuit formed by the conductor 18, the electrode 19 andthe conductor 20 with the electrode '15, and consequcntly with the element 21 and from the latter to the terminal conductor 25, through the insulated bushing 26 in the diaphragm 3. und through the insulated bushing 27 in the top of the cap 2, the latter named bushing being secured in position by the binding screw 2B, and a suitable nut thereon.

Conseipiently the element is ener ized and so the fluid is heated in which con ition the fluid enters the cap 2 and discharges therei and the parts suppe 5 chamber,

from through the nozzle 24. When the fluid is cut olf, and the chamber l is no longer supplied with the same, the valve 7 is relieved of its upward pressure whereby it' closes on its seat. The lever 12 then lowers and with it the bracket 14 whercby'the con-1` tacts 17 are separated and the electric current is broken whereby the element 21 is no longer energized. The element 21 in its ari .rangement 1n the casing, which latter is constructed of metal avoids the formation of an induction in-said casing when' operated by analteraating current.

By. locating the member 3 and the valve rted by said member at the end of the fluid-receiving chamber farthest remote from the tluid-1nlet,the [luid must Afill the said chamber before the cur-l rent is turned on, and, hence, all liability ofv i damage is thus obvia-ted. i i

said valve. for forming an electric circuit 'and energizi said element. 4 1

2. In a lui heater, contacts, movable and stationary carriers for said contacts rpectively, fa valve, a lever freely connected with the stem of said valve for operating the movable `barrier, means for energizing said contacts, a fluid receiving chamber, a heatin'g element` therein, a-valve in said chamber at the end farthest remote from the entrance of the lluid and adapted to be opened by the intlow of. fluid and operate said lever, and an electric circuit for said heating element.

3. In a fluid heater, a fluid receiving chamber, a valve therein at the end remote from the entrance of the fluid and which is ada ted to be opened by the inflow of the flui into said chamber, a diaphragm in said chamber, a lever mounted on said diaphragm and connected with the stem of said valve, an electric contact adapted to be carried by said lever and movable there with, an opposite contact carried byl said diaphragm, electrodes connected wit said contacts, a hea-ting element in said chamber, the same being connected with the adj acent electrode, and an electrical conductor connected with the other electrode, and an electrical connection between 'the movable 4contact andthe last named electrode.

4. In a fluid heater, a fluid receiving chamber having a fluid-inlet at one end,"-a cap therefor at the-other end, a diaphragm between said cap and the adjacent end of the chamber and having o ening'with valve seat, a contact supporte from said diaphragm, a spring-pressed valve, a. pivoted lever movable through the valve Stem, a. con-` tact carried thereby, a heating element in said chamber 'connected withone of said contacts, .and awire within said cap connectin the other contact with an electmde on sai cap.
